As the conservatives say, businesses shouldn't get involved in politics. her business was acting.
The question is -- "should she be cancelled because of something she Tweeted over pronoun usage". I would say No.
Likewise I don't support liberal actors being cancelled for something they Tweeted.
***Assuming that the Tweets don't directly urge physical harm to others or violence in a community.
These people are tweeting their political views as individuals.
Business should not get involved in politics -- individuals tweeting their views is different than a business pushing politics. Individuals should not use their employer's accounts, property or facilities for pushing their personal political views.
